Kit composition

This kit contains two 8 GB DIMMs for a total of 16 GB of DDR4 desktop memory. It is aimed at builders who need a straightforward capacity upgrade for everyday computing tasks. The modules are unbuffered and non-ECC, matching standard consumer motherboard slots.

Sustained operation

Rated at DDR4-2133 with a CAS latency of 15, the modules run at 1.20 V under continuous load. The PC4-17000 bandwidth rating reflects steady-state throughput rather than a short burst figure. No heat spreader is mentioned, so thermal behaviour depends on case airflow alone.

Installation notes

Each stick uses the 288-pin DIMM form factor and seats in a regular DDR4 slot. Because the kit is unbuffered and non-ECC, it will not work in platforms that require registered or error-correcting memory. Buyers who need ECC support or registered DIMMs should look elsewhere.

Questions about this item

How much heat does the 1.20V DDR4 kit produce when running all day?

The modules operate at the standard DDR4 voltage of 1.20V, so heat output stays low during continuous use. No active cooling is required in a normally ventilated case.

What must my motherboard provide for these 288-pin DIMMs to work?

Your board needs two free DDR4 DIMM slots that support 2133 MT/s unbuffered non-ECC memory. The kit installs directly with no extra cables or drivers.

Will the CL15 timing work with older DDR4 sticks I already have?

The motherboard will run all installed modules at the slowest common speed and highest latency. Mixing CL15 with slower sticks is functional but reduces overall bandwidth.
